ABSTRACT:
A two part system for fastening a dental prosthesis to the jaw bone having as a first part, an externally threaded thin wall sleeve which resides entirely within the jaw bone. The threads or other surface features are confined to the area near the point where the prosthesis enters the jaw bone. The sleeve has integrally, or accommodates, a non-threaded stem which extends relatively deeply into the jaw bone. The inner bore of the sleeve is a cone of a mechanically self locking taper. The second part, which extends outwardly from the jaw bone through the gum tissue, has a mating external taper which is driven within the sleeve to be locked therein. The second part supports an artificial tooth, bridge or other dental appliance. The concept also is applicable to a prosthetic device for any body joint.
